Why on earth are you thinking that artifacts have any bearing on timewalking dungeon of all things.
I'm really failing to explain myself! Let's try to break it down:
* No weapons will drop in Legion; we are using artifacts throughout.
* Timewalking dungeons currently can drop weapons.
* They are likely to continue to drop weapons going into Legion, because people below 100 can do Timewalking as well.
* I think it's unprecedented to have loot tables that vary based on the participant's level.
I may be wrong on that.
* Therefore, it is reasonable to assume that if you're over 100 and go into a Timewalking dungeon, you may get a weapon drop that is of no use to you.
The thing is, there's lots of potential solutions to this that I can see, but I'm not aware of any real precedence for this sort of thing, so I'm curious how Blizzard would do it:
* Remove all weapons drops from Timewalking dungeons for all levels
* Implement changing loot tables based on participant level
* Just not care and have weapons drop that aren't of use for 100+ players
* Something else.
